Webb28 apr. 2024 · OpenCV Smoothing and Blurring I’m pretty sure we all know what blurring is. Visually, it’s what happens when your camera takes a picture out of focus. Sharper regions in the image lose their detail. The goal here is to use a low-pass filter to reduce the amount of noise and detail in an image.

For example: If dx=1 and dy=0, we compute the 1st derivative Sobel image in the x-direction. chiropodist ireland
